Questions about C.A.S. III

You can expect to be able to use them for about 2 years. Factors such as the number of transmit signals do not affect the life as much as long cold periods do.

Standard CR2032 button cells are used for the wireless components. These button cells can be stored unused for up to 10 years (heed label). However, the button cells should be replaced every 2 years according to the battery warranty (manufacturer providers a 2-year no-leak guarantee from the time of first use). We recommend the use of brand-name batteries (Panasonic, Varta, Duracell etc.).

Memory aid: Replace the batteries, for example, with every vehicle inspection and/or gas inspection.

A weak battery (< 2.6 V) is indicated by an acoustic signal (5 seconds) on the central control unit triggered by the wireless component and a visual signal (the red ‘transmit LED’ only goes out after about 30 seconds) on the transmitter. If one button cell is weak, it is best to replace all of them.

If a 5-second-long signal tone is emitted by the alarm system, a taught-in accessory part requiring a battery change was actuated immediately before that. This is also indicated by a 30-second-long visual signal on wireless magnetic contacts and radio cable loops.
Occurs:

• when wireless magnetic contacts on doors/windows/hatches are opened/closed
• when remote transmitters and conversion boards are actuated (‘remote controls’)
• when the cable loop is used in the holder

If a wireless accessory sends an alert, the other button cells are probably just as old. A complete change is recommended. Please take button cells to a battery recycling centre or collection point. They can be recycled there.

You can replace the batteries (CR2032 button cells) in wireless components yourself.

To change the transmitter battery in a wireless magnetic contact:

Lever open the housing at the notch on the long housing side. Take out the printed circuit board and replace the battery with one of the same type (CR2032). Ensure correct polarity when inserting the battery.

To change the transmitter battery in a radio cable loop:

Open the housing by removing the screws on the bottom. Replace the battery with one of the same type (CR2032). Ensure correct polarity and correct alignment of the rubber seal when inserting the battery.

To change the transmitter battery in a wireless remote control:

Open the housing by removing the screws. Replace the battery with one of the same type (CR2032) and ensure correct polarity when inserting.

Please make sure you don’t leave any fingerprints on the button cells when you change the batteries (this can lead to a higher self-discharge rate). Please take button cells to a battery recycling centre or collection point. They can be recycled there.
